Ch 9 Review

What happens to the resistance as the temperature of the conductor increases?

• increases
• decreases
• stays the same
• none of the above

The unit for the rate of current

• Herzt
• joules
• ampere (amps)
• watts

What is produced around a wire through which a current flows?

• resistance
• electric charges
• solenoid
• magnetic field

Which of these will have the greatest resistance?

• short wire
• long wire
• wire with great diameter
• decrease in temperature

The strength of the electric fields get weaker 

• the farther away they are from the charge
• closer they are to the charge
• distance does not matter - it could be farther or close
• none of the above

What kind of circuit is this?

• Series
• Consecutive
• Parallel
• Training

What does the voltage on a battery mean?

• The speed of electron flow through it.
• How tough it is for electrons to flow through it.
• The amount of energy given to the electrons.
• The amount of energy taken away from the electrons.
